Abstract: Systems and methods are disclosed that provide femto-based wireless coverage in a communication network. This can involve providing an interworking function that communications with a femto base station or femto cell to provide connectivity to the core network. The interworking function can provide service and mobility management where a femto cell (such as a home node B (HNB)) is served concurrently by an IMS core and a legacy core. The interworking function can also provide service through a femto cell to a variety of mobile nodes such as legacy devices and IMS capable devices. The interworking function also provides the ability for handoffs to occur between the core networks and between a femto cell and a macro cell.

Abstract: Systems and methods for providing voice communications and data communications are provided, including: receiving an attach message from a mobile node indicating the mobile node can fallback from a first radio access technology to a second radio access technology and including location information identifying a location of the mobile node, the attach message received via the first radio access technology; sending a translated location updated message to a remote switching device; receiving a service request message from the mobile node, the service request message requesting initiation of a voice call, the service request message received via the first radio access technology; and based on the service request message and the indication that the mobile node can fallback to the second radio access technology, setting up the voice call with the mobile node via the second radio access technology.

Abstract: Systems and methods for transferring a session or components of a session in a communication network are provided. The components of the session include media flows and control over the media flows. The user can initiate a transfer of a existing session with a mobile device such as user equipment (UE) to one or more devices that may lead to fan-out or fan-in to multiple devices. This can include separating the delivery of media from the control of the delivery. For example, a UE can be designated a controller to control another UE, such as a television (TV). In providing the capability to transfer these sessions, a gateway is used to implement network functions that allow the streaming to be controlled and delivered to the respective UEs. In some embodiments, the gateway can be flexible and its operation modified according to messages it receives.

Abstract: Systems and methods are provided that allow inter-working between communication networks for the delivery of service to mobile nodes. A gateway is provided that communicates with a femto cell to extend service to an area that otherwise does not receive coverage from a service provider. The femto cell is a small scale base station used to provide coverage over a small area (such as a home or business), and connect to a home or enterprise network. The femto cell provides service for a mobile node and a gateway permits communication over a broadband network. The gateway integrates the mobile nodes connecting via a femto cell into the service provider's network. The gateway also allows provisioning of services and applications, control of service levels, and provides seamless handoffs to macro base stations and other types of access technologies such as Wi-Fi.

Abstract: Systems and methods to virtually and securely extend voice, data, and video services as well as applications on communication networks is provided. An access gateway device is used to provide interworking and extension of services from an enterprise network or a hosted enterprise network to a public network such as an IP Multimedia Subsystem (IMS) network. The access gateway device can also enable handoffs between an enterprise access point and the service provider's radio network while maintain the user's session. The access gateway can also extend services from the enterprise network to the service providers network and vice versa.

Abstract: Advanced communications features are provided in a mobile communications network having at least one mobile switching center and at least one mobile station subsystem. The mobile switching center and mobile station subsystem each communicate signaling messages according to a mobile signaling protocol.

Abstract: Systems and methods are provided that allow the delivery of location based services within a communication network. The location information can be retrieved using information from the mobile node when the mobile node registers in the network. The location information can then be cached or stored in one or more places in the communication network and correlated with the mobile node's addressing information. If a request for location based services is received without location based information, the gateway can use location based information regarding the mobile node to provide location based services. The gateway can enable non IMS mobile nodes to obtain IMS location based services or incompatible mobile nodes to obtain location based services.

Abstract: Methods and systems are provided for combining a plurality of data streams into a single data stream for sending to a wireless user. According to the invention, using one or more data mixers, two or more video streams are combined into a single video stream and provided to a wireless user, and/or two or more audio streams are combined into a single audio stream and provided to a wireless user. The streams are optionally decoded and handled in raw format by the data mixer, and at least some of the streams may be buffered in a queue so that “slipping” or synchronization problems can be addressed. The method and system can process media data such as video, audio, text, or other media data.

Abstract: In some embodiments, a gateway in a communications network is provided including a subscriber interface and a Session Initiation Protocol (SIP) registrar; wherein the SIP registrar: receives a first register message as a result of a request associated with a user and a mobile device seeking network authentication; and sends a request for subscriber information to the subscriber interface; the subscriber interface: retrieves the subscriber information from the subscriber database; and sends the subscriber information to the SIP registrar; the SIP registrar further: sends challenge information including a password request and a request for predetermined response information previously selected by the user to the mobile device; receives a second register message including user response information in response to the challenge information; and authenticates the mobile device and the user based at least in part on whether the user response information matches the predetermined response information.

Abstract: Systems and methods for providing interaction management to network devices in a communication network are described. A gateway may be used to implement the interaction capabilities on packet flows for IP multimedia subsystem (IMS) and multimedia domain (MMD) architectures. Interaction managers and proxy agents can be provided by the gateway, such as a service control interaction manager (SCIM). The SCIM can be a layer and manage interactions between network devices such as mobile nodes and application servers and can provide abstraction of network devices. This can allow the gateway to provide interworking between network devices and handle mobile nodes with different capabilities.

Abstract: Systems, methods, media, and means for hiding network topology are provided. In some embodiments, methods for hiding network topology are provided, the methods including: receiving a message including topology information from a sender; removing at least part of the topology information; associating the removed topology information with an identifier; saving the topology information; sending the message to a receiver; receiving a response from the receiver; retrieving the removed topology information based on the identifier; inserting the removed topology information into the response; and sending the response to the sender.

Abstract: Systems and methods for managing packet flows in a communication network are provided. Packet information can be cached on different levels and used to avoid external queries. The cache information can also be correlated with other types of information, such as location information, to be able to serve that information quicker than if one or more external queries were to be made. A demux manager can provide routing and session setup, by routing packets that already have a session to the session manager and assigning packets to a session manager if they are not already assigned to a session. The tiered architecture also provides scalability to many users and minimizes delays even during high call volumes because the load can be distributed well across the gateway's resources.

Abstract: Methods and apparatus are provided for reducing call setup delays resulting from non-call related signaling. In session initiation protocol (SIP) messaging, SIP session setup messaging can have the same priority for placement on the airlink to a mobile phone as other non-call session setup messaging. Method and apparatus for providing priority to call session setup messaging are providing, and in some cases, emergency call setup messaging. By providing priority to call setup messaging, delays that might result from being stuck in a queue behind non-call setup messaging can be reduced.

Abstract: Systems and methods for providing dynamic changes to a packet flow in a communication network are described. The dynamic changes can include upgrading and downgrading quality of service (QoS), adapting the stream to a receiving device, modifying the stream to counter-act changes in an air interface, and modifying the stream to accommodate an inter-technology handover. These changes can be provided by inspecting packets at a gateway and setting up a proxy for multimedia stream packet flows. The proxy can coordinate transcoding to take place to change the stream. The gateway can also monitor conditions at the mobile node using a real time control protocol or other applicable protocols.
